Firefox need to update immediately – fake alert

We consider our duty to warn all Mozilla Firefox users about severe danger hidden in the message you see depicted at the screenshot below that says: “Firefox need to update immediately!” You need to realize, of course, that this is nothing but the fake alert, which is not associated with Firefox browser (whatever version you use). This is a virus that has been developed by hackers who want to bring malware into your system through fake update of this well-known and widely used browser.

Firefox need to update immediately! Your version of Firefox (18.0) is vulnerable and needs to be updated. Attack pages try to install programs that steal private information, use your computer to attack others, or damage your system. Some attack pages intentionally distribute harmful software, but many are compromised without the knowledge or permission of their owners.

According to our analysis, ransomware of Urausy type is brought into system after user agrees to click “Update” button. This is a very dangerous type of virus, and there’s no guarantee that other malwares can also be spread in such a manner. Hence, if you’re an active user of Mozilla Firefox browser, please be very careful when you might occasionally encounter such fake browser update alerts. Make sure that you update your browser only via the official web-site.

If you encounter the message that says “Firefox need to update immediately” then pay attention to the poor English grammar used in this warning. Surely, it was not developed by professionals. On the contrary, it is the products of cyber crooks who want to infect your computer tremendously. Therefore, make sure to ignore all such fake browser update alerts and scan your system with our recommended security software – GridinSoft Trojan Killer.
